Bussmann Modular Ferrule Fuse Blocks Simplify Installation and Enhance Safety

April 9, 2015 at 4:29 pm  •  Posted in Machine Builder  •  0 Comments

The new line of ferrule fuse block products for Class CC, supplemental, Class H(K), Class J and Class R fuses are fully modular with a snap-together design, providing tool-less assembly of multiple pole blocks at point-of-use to save inventory and reduce assembly time (also available in factory assembled 1-, 2-, and 3-pole configurations). Each block has provisions for DIN-Rail mount and panel mount applications, allowing the same block to be used for multiple applications and lowering inventory costs. Additionally, the new ferrule fuse blocks have a compact design that minimizes the product footprint, allowing for the most efficient use of panel space.

The optional covers enhance the overall safety of the panel assembly, with IP20 finger-safe ratings for the full wire size range of each product. The covers have an enhanced lockout/tagout feature, compatible with a broad array of lock designs. Each cover has provisions for a snap-in marker label for easy circuit identification. Covers are also available with optional open circuit indication to reduce troubleshooting and maintenance time.


  • Overcurrent protection of control circuits, lighting circuits, meter circuits, fan and motor circuits and control transformers.
  • Overcurrent protection of HVAC/R equipment, factory automation equipment and industrial machinery.
  • Alternative energy applications at 1000Vdc (BPVM products) in high ambient environments where temperature rise is a concern.

Features and benefits:

Small, compact footprint

  • Compact footprint minimizes panel space requirements
  • Most platforms have the smallest width dimension in the industry to fit more poles within the panel

DIN-Rail and panel mount flexibility

  • All SKUs can either be DIN-Rail mounted or panel mounted, increasing versatility and ease of application for panel builders

Modular design

  • Tool-less ganging of multiple poles at point-of-use eliminates the cost of carrying multiple SKUs for different applications

Clear IP20 finger-safe optional cover

  • Enhances safety and prevents incidental contact with terminals
  • Clear cover with probe holes allows for easy fuse inspection and thermal imaging without cover removal to reduce maintenance time

Lockout/tagout feature (with optional cover)

  • Enhances maintenance safety

Open fuse indication (with optional cover)

  • Reduces troubleshooting and maintenance time

Universal marker labels

  • All covers have provisions for marker labels for easy circuit identification
  • Class H/J/R fuse blocks have marker label provisions on each end of the block and under the fuse for clear circuit labeling to reduce maintenance time
